The study was conducted to find out the effects of mating systems and environmental factor. on the live weight gain of the crossbred from Charolais x Korean native cattle in order to establish the reasonable scheme for spreading the crossbred cattle. The crossbred and the native cattle raised in the Ganghwa Island, Gyeonggi province were measured body weight, withers height, hip height, pine height, body length, chest width, chest depth, rump length, hip width, Churl width, pine width, shank circumference and chest girth, and the farmer`s feeding and management conditions were checked and analyzed from March to October in 1980. The results obtained are summarized as follows: 1. The body weighty of the cattle at the age of 6 months were significantly different between the crossbred and the native cattle (p$lt;0.01) as 208.11 ㎏ in the crossbred bulls and 140.00㎏ in the native bulls, and 180.81㎏ in the crossbred heifers and 108.67㎏ in the native heifers. The body weights at the age of 12 months showed significant difference; between the crossbred and the native cattle (p$lt;0.01) as 404.06㎏ in tire crossbred bulls and 296.60㎏ in the native bulls, and 336.18㎏ in the crossbred heifers and 180.14㎏ in the native heifers. 2. The body measurements of pine height, body length, hip width, shank circumference and chest girth showed significant differences between the crossbred and the native cattle at the age of 6 months. The body measurements at the age of 12 months such as pine height, body length and thud width were different significantly between the crossbred and the native cattle.

The study was conducted to obtain some genetic information on crossbred. from crossbreeding of Korean native goats and Saanen goats. Eight hundred and seventy head, of purebred and crossbred goats raised at the Livestock Experiment Station from 1969 to 1975 were investigated to get the data on their body weight, body measurements and milk yield. Those data were analysed to estimate the additive and non-additive effect; as well as maternal effects by different mating systems. The results obtained are summarized as follows ; 1. The additive effects on body weight, withers height, body length, cheat girth and milk yield in single crossing(SN) of Korean native goats and Saanen goats were estimated 86.54, 106.89, 104.95, 98.44, and 89.41%, respectively, and non-additive effects 13.46, -6.89, -4.95, 1.56 and 10.59%, respectively. 2. In the second generation of F₁ back-crowed to Saanen breed for grading up S (SN) the additive, non-additive and maternal effect, were estimated 82.26, 5.94 and 11.80% for body weight, 102.10, -3.13 and 1.02 for withers height, 105.00, -2.35 and -2.64% for body length, 99.32, 0.77 and -0.09% for chest girth, 105. 11, 4.38 and -9. ~19$quot;/o for milk yield, respectively. 3. In the third generation of S (SN) back-crossed to Saanen breed for grading up S (SSN) non-additive and maternal effects were estimated 8-1.17, 2.92 and 12.91% for body weight, 101.66, -1.5% and -0.13% for wither; height, 102.58, -1.13 and -1..15% for body length, 101.24, 0.38 and -1.62% for chest girth, 103.73, 1.88 and -5.6% for milk yield, respectively.

The prevalence of antibody to Getah virus was serologically followed among those horses in Korea. Blood samples were taken from 575 horses in February and 462 horses in September, 1985. Overall percentage of horses with seropositive to Getah virus was 37% in February and 47% in September. The data suggest that the Getah virus infection is endemic in Korea and the increase in prevalence may be associated with the seasonal activity of arthropod vectors. This entails preventive precautions of the horses against this viral infection before the entry into Korea.

A BLUP animal model genetic evaluation system was developed to evaluate milk yield. fat yield and fat percentage by taking into account characteristics of the Korean Holstein cattle population. Records of all lactations for each cow were included in the analysis. In order to he included in genetic evaluation, sire and dam of bulls should have two or more progeny in the identification file and imported hulls or semen should have records of daughter, in Korea. The numbers of records and animals tested and evaluated in Korea Animal Improvement Association and Dairy Cattle Improvement Center of National Livestock Cooperative Federation were 41.333 and 24,539, respectively. Solutions for fixed genetic group, random herd year season, additive genetic, and permanent environmental effects of the proposed models were obtained by the iterative conjugate gradient method for a sparse linear system. Fixed genetic groups included nationality of unknown parents, which were form Korea. U.S., Canada, and other countries. Instead of using the element of inverse of the coefficient matrix, accuracy of additive genetic effects were iteratively estimated a, in the USDA animal model except for excluding contributions from sire-herd distribution.

The first outbreak of Aujeszky's disease(AD) was identified from piggery located at the southern part of Korea in July, 1987. This piggery suffered from a significant economic loss caused by unexpected piglet mortality and reproductive failure. Etiologic viral agents were isolated from tonsil and spleen of the infected piglets, and the isolates produced a typical cytopathic effects of herpesvirus with giant cell formation when inoculated in many different cells. Subsequently the field isolates were characterized as suid herpesvirus I by cross-neutralization test and indirect fluorescence assay utilizing specific monoclonal antibody, and were proved to be a pathogenic strain of AD virus(ADV).

The present surveys were conducted in attempts to investigate the health situation of horses in Korea through mass-screening the samples serologically, bacteriologically and clinically. A total of 575 horses were sampled randomly, comprising 126 from the Korean Horse Affairs Association, 288 from the Korean Equestrian Federation and 161 from the Jeju ponies. Each of the samples taken was tested for diagnoses of 18 horse diseases including African horse sickness. Summarised below are the results obtained from this surveys. 1. From results of the serological survey it is evident that Korea is currently free from African horse sickness, dourine, glanders, vesicular stomatits, equine piroplasmosis, equine viral arteritis, Venezuelan encephalomyelitis and contagious equine metritis. Constant vigilence with strengthened quarantine measures is thus vital for maintaining freedom of any those diseases in Korea. 2. No clinical case was observed with any of signs or symptoms of infectious lymphangitis, anthrax and infestations with ringworm, mange or scab. However, continuous follow-up is required for establishing the evidence of no occurrence of the diseases in Korea. 3. One case of seropositive to equine infectious anemia may fully justify systematic and regular testings for the whole population of horse in Korea. 4. It is manifested that equine rhinopneumonitis, Japanese encephalitis and Getah virus infection are well established in Korea, together with the presence of equine infectious abortion(Salmonella abortus equi). This strongly entails preventive precautions before entry into Korea for the horses participating in the 1986 Asian Games and the 1988 Seoul Olympics.

2000년대 가축질병방역대책

설동섭 한국축산학회 1986 한국축산학회지 Vol.28 No.5

1. As many as 82 different kinds of animal infectious disease are present in Korea, rendering direct losses of 50 billion won per annum to the livestock industry. Moreover, the whole economic losses due to those diseases reach 421.6 billion won, corresponding to 17.5% of the total production of 2,400 billion won in the Korean livestock industry. 2. For the animal health situation in Korea, bacterial diseases of large animal are in the stage of eradication through national control campaigns, while viral diseases in other animals including poultry, currently dependent on voluntary control by livestock owners, stillrequire more drastic and long-term based control measures for eventual eradication. 3. Organisations for animal disease control are well structured, but lack in functional systematisation. Thus, extension of the organisations and generalisation of their functions are necessary for the improvement of efficiency in animal disease control activities. 4. In the system for animal disease surveillance, its core centre is the Veterinary Research Institute and the surveillance network comprises a total of 1992 organisations throughout the country, including provincial animal health laboratories, regional rural extension services, and community verterinarians. Reports on disease outbreaks and related information are collected for analysis and early-warning. However, improvement in the efficiency of animal disease control must seek more active cooperation and endeavors from the local authorities concerned. 5. There are 332 processing plants for animal products in the country, where some 400 veterinary officers are working for sanitary inspection. Urgently required in this respect are the modernisation of facilities and equipment at slaughterhouses and milk collecting centres, and the regional integration of those plants that are dispersed nationwide in small scale. 6. To meet the current situation of animal health and the hygienic status of animal products to the level of those in developed countries by the year of 2000, every effort will have to be made for the computerisation of animal disease surveillance system, the scientific application of disease control measures, the independence of research activities from those for biologics control and disease diagnoses, the compulsory practice of vaccinations and serological testings for animals on sale, and finally for the implementation of special measures that will lead to free movement of animal products.

가축개량에 관한 한우의 개량방안

설동섭 한국축산학회 1981 한국축산학회지 Vol.23 No.5

The problem of how to improve effectively Korean native cattle for beef production has been discussed controversially among Korean geneticists for more than 20 years since 1960. The main point of controversy was to determine which procedure of both purebred selection and crossbreeding with exotic beef breed should be applicable for more effective improvement of Korean native cattle. It was very difficult for us to decide definitely the exact one of both procedures because of having their merits or defects respectively in view point of cattle breeding policy. In this paper, the achievements of Korean native cattle improvement for past 70 years were reviewed and the outline of new scheme proposed for future programme. The content of this paper was summarized as follows; 1. Korean native cattle increased about 69 % in the body weight of adult female more than 60 years ago as shown on table 1. This increase came mainly from combination of bull selection and improved feeding condition, but it was not possible to estimate separately how much the genetic gain affected on the increased body weight of Korean cattle. $lt;표생략$gt; 2. The goal of improvement was established on basis of Korean cattle performance from Alpine experiment station in which progeny test is carried out, as shown on table 2. The goal was divided into 3 steps by stage for long term programme. $lt;표생략$gt; 3. It is proposed that the main procedure for Korean native cattle improvement should rely mainly on the purebred selection as well as partly on the crossbreeding with exotic breed including hybrid utilization. The proportion of both procedures would be determined depending on the policy of government. It suggested that the crossbreeding should be conducted very carefully taking measurements for possible problems occurred in practice. 4. The breeds of beef cattle for crossbreeding of Korean native cattle should have following conditions; suitable to small herd feeding system, in early maturity fattening, of large type, in good appetite, in gentle nature, in good mooring, in similar colore to Korean cattle, in high motherbility, in high feed efficiency and in high percentage of Lean meat. According to above criteria, Charolais, Simmental in mainland and Brahman in Jeju island would be recommendable for crossbreeding of Korean native cattle, because those three breeds already expressed good result in crossbreeding experiment. 5. The organization for breeding of Korean native cattle should be strengthened for more effective improvement. ·To establish $quot;Korean cattle improvement commission$quot; to be responsible for all matters related to cattle improvement. ·To integrate the performance test projects of Korean native cattle carried out independently in each organization: Alpine experiment station, Daekalyong and Unbong branch stations of National livestock Breeding Station. ·To let provincial breeding stations join positively in the performance test project of Korean bull. ·To enlarge the business of Korean Animal Breeding Association. To establish $quot;Breeding Base$quot; in farm area for progeny test. 6. The functions of organization for Korean cattle breeding should be strengthened for acceleration of improvement as follows; ·To enlarge the capacity of semen storage in Artificial Insemination Institute. ·To establish the performance test committee for controling Korean cattle. improvement project. ·$quot;Korean Animal Breeding Association$quot; to hold $quot;National Livestock Contest$quot; ·Government to transfer all business of improvement to the organization. ·Scientists of universities and research institutes to join positively in the business of organization. 7. The government should support strongly the activity of organization. ·To rearrange and support the organization. ·To support the budget required for purchasing superior bull and cow from $quot;National Livestock Contest.$quot; ·To support positively $quot;Korean Cattle Improvement Project$quot; by $quot;Livestock Encouragement Fund.$quot; ·To coordinate and support the business between organizations.

각종 Silo 에 의한 산야초 Silage 제조시험

김형철,설동섭 한국축산학회 1960 한국축산학회지 Vol.2 No.1

The cost of building silo was lowest for pit silo, whereas it eras highest for concrete silo, but concrete silo seems to be cheaper than muddy silo in a stand-point of their using age. Temperature of silage fermentation was different of about. 4℃. between underground silo (21-23℃) and upperground silo (25-27℃.) in constant temperature of fermentation end period, while between silo covered in with vinyl (21-23℃.) and one no covered (23-27℃.) was different of about 2℃. But in muddy brick silo it was 40℃, above and then showed a sign of putrification due to be attacked by air outdoor through broken parts of wall and to be taken moisture from silage. For spoilage percentage of silage muddy brick silo was 42.2% and so was not found of use at all, but others all were 5% below, especially pit vinyl silo lowest in 1.13%. Treatment of silo for spoilage was significant in evel of 1% and differences between mean value of spoilage percentage of silage, excepting between them of concrete silo and muddy brick vinyl silo, were higher than L. S. D≒1.0780 and so were significant in level of 5%. Among constituents of wild grass silage exude protein was increased. more half than that of wild grass, and therefore, wild grass silage was resulted. higher than corn silage in nutritional value. For acid yield of silage from silos which silage was spoiled lees contained more lactic . acid and was in trend to be good in color and odor. Palatability of silage to Korean cattle, excepted of that from muddy brick silo, was not so different between siloes. For this reason the fact was that silage consumption of Korean cattle was 94% above in all, but the rattles did not take silag from muddy brick silo at all.
